Chemshun Tell you how is Polypropylene Pall ring packing working in packed tower

  Polypropylene Pall ring packing is widely used, which increases the direct economic benefits of chemical plants. Let us understand the application of polypropylene Pall rings in PVC. It has the advantages of simple structure, large empty tower speed change range and simple manufacture. Packed towers with a diameter of less than 1 meter are still widely used in PVC production enterprises. In the production of PVC, this packed tower usually uses corrosion-resistant non-metallic materials, such as ceramic packing. The factory started to replace the ceramic packing with polypropylene Pall rings, which achieved good results, and there was no tower blockage caused by packing corrosion. Due to the light weight of the polypropylene Pall ring packing, the stacked weight is only 1/10 of the ceramic Raschig ring and 1/7 of the ceramic Pall ring, so the weight of the packing in the tower is greatly reduced, and the polypropylene Pall ring will not break and will not break. Produces debris t...

Cutting method of wear resistant ceramic lining

图片
    The wear  resistant ceramic lining tile  is generally made according to the mold during production, and  the shape of the wear-resistant ceramic tile  is relatively regular, so it needs to be cut during the construction process. However, it is difficult to cut alumina ceramic tile , because the hardness of alumina ceramics liner  is high, and the Rockwell hardness of alumina ceramic linings with an alumina content of more than 92% is above 80, and the hardness of general grinding wheels is not as big as it. It cannot be cut, only with a diamond saw blade.   We use diamond blades with high hardness for cutting. There are large desktop and handheld cutting machines, as long as they are well protected during cutting, do not cut the skin by the cut pieces. Then talk about how to cut, this is the key point. But our technicians told us that when the high-speed rotating blade contacts the wear-resistant ceramic liner at the center, the cera...

How to install abrasion ceramic cylinder pipe in the integrally formed steel pipeline ?

The integrally formed wear resistant ceramic pipe produced by Chemshun Ceramics is mainly divided into three steps: ceramic ring splicing, ceramic ring pasting and grinding. (1) Alumina ceramic splicing: The ceramic  rings that have passed the inspection are spliced with 502 quick-drying glue according to the requirements of the drawings to ensure that the interior is flat and there are no large gaps (2) Alumina cylinder pasting: the flanges on both sides of the pipe are wrapped with kraft paper, and the glue is glued in the pipe with the adjusted adhesive to ensure that it is even, and then the glue is glued on the spliced porcelain ring pipe to ensure that the pipe is intact once Sexually stick to the inner wall of the pipe. After fixing, check whether there is misalignment and glue leakage on the inner wall of the pipe, and place the pasted pipe in the designated position after checking. The ceramic paste should be operated in strict accordance with the drawing, and the ceramic ...
